ISAAC F. HOLMES AND HORACE A. HOLMES, OF MANTON, MICHIGAN.

CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 600,151, dated March 8,1898.

Application filed June 28,1897. Serial No. 642,593, (No model.)

To all whom it may concern:

Be it known that we, ISAAC F. HOLMES and HORACE A. HoLMEs, citizens ofthe United States, residing at Manton, county of Wexford, State ofMichigan, have invented a certain new and useful Improvement in Ohurn-Dashers; and we declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification. 7

Our invention relates to an improvement in churn-dashers, and especiallythat class adapted to be employed in connection with the ordinaryupright churn.

It has for its objects, first, to provide a device that may be employedin connection with the dasher of an upright churn by which air may beforced through the cream to the bottom thereof,where it is permitted torise to the top and thus create therein a violent agitation, whichmotion assists in separating the butter particles from themilk,and,second,to provide an attachment to be used in connection withthe dasher during the first part of the churning that can be easily andquickly removed therefrom preparatory to the gathering operation.

With these objects in view the invention consists in the generalconstruction and arrangement of the parts, as will be hereinafterdescribed, and particularly pointed out in the claims.

Referring to the drawings for a better understanding of our invention,Figure 1 1111151 trates our improved attachment in position for use.Fig. 2 shows it in sectional elevation, illustrating its form and mannerof support.

Like letters of reference refer to corresponding parts in both figures.

A indicates the main body of the attachment, B an ordinary dasher, and Othe handle thereof. This dasher and its handle are well known in theart, and as they form no part of our invention will only be referred toby way of making the application of our attachment better understood.

The main body of this attachment is pref erably constructed in the formof an inverted circular trough like disk having an inverted- U-shapedcross-section, as shown in Fig. 2. The two lower edges or b of thetrough are made to occupy the same horizontal plane, so that as the diskis forced downward upon the surface of the cream,as hereinafterdescribed, the air which fills the trough or concavity will be carrieddown through the cream.

0 and d are two short springs secured at opposite sides of the disk attheir lower ends and have their upper free ends turned inward anddownward to form the latches e and f, which are adapted to engage overthe edge of the cross-bar to hold the convexed side of the disk snuglyagainst the under side of the dasher. In order that the catches may notslip over the sides of the bar upon which they are engaged, notches maybe provided in the ends of the bar,within which the springs may be madeto engage. This construction permits the device to be readily removedfor the purpose above pointed out as well as for sanitary reasons,enabling it to be cleansed much more thoroughly.

We have found that by use of this attachment, substantially in the formshown, the time occupied in separating the butter from the milk can bereduced four or live times. It maybe understood, however, that theparticular form and means of support may be Varied to some degreewithout materially affecting the results, and we desire to have itunderstood that any slight modification that may be found necessary inorder to adapt the attachment to various forms of dashers can be madewithout departing from the spirit or scope of our invention.

From the foregoing the operation of our invention may be readilyunderstood. WVhen it is desired to attach the device, the catches arespread sufficiently to engage over the upper edge of the bar, the endsof which are clamped firmly between the springs,and when they arereleased the inclined under faces of the notches draw the convexedsurface of the disk snugly against the under side of the dasher. Whenthis is done, the device is in position for use, and as it is insertedinto the cream the edges of the trough engage therewith, retaining theair that fills the concavity, which is forced to the bottom by thedownward movement of the dasher Having thus described our invention,what We claim is- 1. A new article of manufacture to be employed inconnection Witha churn-dasher consisting of an inverted annularreceptacle having spring-catches secured to the outer edges of saidreceptacle, and adapted to removably engage with said dasher,substantially as described.

22. The combination with the handle and cross-bars in a churn-dasher ofan inverted annular receptacle, springcatches having their lower endssecured to the outer edge of said receptacle, and their upper endsterminated with inclined catches to engage the cross-bar of said dasher,substantially as described.

In testimony whereof we sign this specification in the presence of twowitnesses.
